Abstract: PURPOSE:To output a signal by means of capacity coupling, by providing a slot on an external electric conductor for screening a radio wave, within the range where no radio wave leaks, and inserting a metallic plate between the slot part and a center electric conductor for propagating a radio wave. CONSTITUTION:When a slot 2 having width (d) and length (l) is provided on the diameter D of an external electric conductor, and wavelengh lambda is propagated, an aixal phase constant and a phase constant of meeting at right angle with said axial direction, on the surface becomes betaZ=(epsilon0Xmu0/LC)<1/2>, betat=(k<2>-epsilon0mu0/ LC)<1/2>, reepectively, (in the expression, L=pimu0D<2>/4, k=2pi/lambda). In case of D/lambda< 0.1, (betat/k)<2>>1, no radio wave leaks from the slot. When a metallic plate 33 is inserted between a center electic conductor 30 and an external electric conductor 31, capacity CM is formed. When size of a slot 32 is set to k<2>=epsilon0mu0/LC or so, and a switch 34 is closed, the whole capacity of the slot is increased by CM, becomes k<2>>epsilon0mu0/LC, and is shifted to a rsonance area. Accordingly, a radio wave is outputted freely by means of capacity coupling from the slot 32 by opening and closing the switch 34.

Title: Transistor power amplifier
Inventor: TACHIBANA MAKOTO
IPC: H03F3/20
Filed: 1981-06-18
Abstract: PURPOSE: To substantially zero a through-current, by changing a response time constant of a driving circuit for turning on and off of an output stage transistor (TR).  
     CONSTITUTION: When a power TR turns on, a diode D 1  of a filter circuit 10 turns off and the time constant of the circuit 10 is a product between a resistor R 1  and a capacitor C 1 . Thus, when an input which turns on power TRS Q 1  and Q 3  is given to driving circuits 3 and 4, an output with a response time constant C 1 R 1  is obtained. When a power TR is turned off, the diode D 1  of a filter circuit 11 is nonconductive. The time constant of the circuit 11 in this case is the product of a resistor R 2  and a capacitor C 1 . Thus, power TRs Q 2  and Q 4  are turned off with a time constant C 1 R 2 . Denoting C 1 R 1 >C 1 R 2 , since the power TRs Q 1  and Q 3  can be turned on after the power TRs Q 2  and Q 4  are turned off, no through-current can flow.
